American Rare Earths has released an updated Scoping Study for the Cowboy State Mine in Wyoming, projecting a 4.5 Mtpa operation with a 26-year mine life. The study reports an after-tax NPV of US$1.07 billion at an 8% real discount rate, supported by increased NdPr oxide production of approximately 2,500 tonnes per annum.
American Rare Earths has reported strong initial assay results from its 2026 Feasibility Study drilling at the Halleck Creek project. The results confirm broad, near-surface rare earth mineralization with a pooled average grade of 3,497 ppm TREO.
American Rare Earths has announced an accelerated pilot plant program for its Halleck Creek Project in Wyoming. The program will involve initial processing in Wyoming via DISA Technologies and Western Research Institute, followed by hydrometallurgical processing and oxide separation at the Saskatchewan Research Council.
